It is designed to check that a threaded hole does not accept an oversized member, confirming the thread falls within the upper tolerance boundary of the 6H classification. Made from steel, this gage is built for repeated use in production and quality-control environments. NIST traceability is included, supporting documented inspection processes in shops operating under ISO, AS9100, or similar quality management systems. A size 1 handle is required for use but is not included with this gage.\u003c\/p\u003e\n\u003cp\u003eThis plug thread gage is suited for use in precision manufacturing, aerospace, automotive, and general metalworking shops where 5\/16-32 UN internal threads must be verified to ANSI and NIST standards. It is a standard tool for quality inspectors, machinists, and tool-room technicians performing go\/no-go acceptance testing on threaded bores in production or receiving inspection settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo Go configuration checks the upper tolerance limit of 5\/16-32 internal threads to 6H class\u003c\/li\u003e\n  \u003cli\u003eNIST traceability certificate included for documented inspection and calibration records\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and NIST standards for thread gage accuracy\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production environments\u003c\/li\u003e\n  \u003cli\u003eSingle-end design for straightforward go\/no-go inspection workflow\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard size 1 thread gage handles (handle sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with size 1 plug thread gage handles.

Before use, clean the threaded bore and gage member thoroughly to remove chips, coolant, and debris that could affect readings. The No Go member should not enter the threaded hole more than two turns under hand pressure alone; forced insertion can damage both the gage and the part. Store gages in a protective case away from other tooling to prevent wear and maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClassification\u003c\/strong\u003e: 6H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGo\/No Go\u003c\/strong\u003e: No Go\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Size\u003c\/strong\u003e: 1 (not included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraceability Certification\u003c\/strong\u003e: NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, NIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 34-266-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51700130611506,"sku":"34-266-7","price":131.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/779c7450469f985e14fa0e06fa85580d.jpg?v=1788386432","url":"https:\/\/voomisupply.com\/products\/spi-34-266-7-no-go-plug-thread-gage-5-16-32-6h","provider":"Voomi Supply","version":"1.0","type":"link"}
